Organic-based devices can be largely mechanically flexible due to the weak intermolecular bonds in the nano-electrons created from them . Unlike these organic materials, minerals such as silicon, germanium, and gallium arsenide can only be used in the structure of electronic devices in crystalline states , in which case covalent bonds make flexibility impossible. Properties such as strength, flexibility, electrical conductivity, magnetic properties, color, reactivity and so on. The beginning of changing the properties of a material by shrinking it depends more than anything on the type of material and the desired property. For example, as the dimensions of a material shrink, some of the mechanical properties of materials, such as strength , generally improve. This increase in strength does not occur only in the range of a few nanometers, and may be due to the strength of several tens of materials. Even one hundred nanometers is much larger than large-scale bulk material. On the other hand, changes in some properties, such as color and magnetic properties, may occur in dimensions of only a few nanometers.
In addition to these two, the state of the energy levels of the electrons around each atom, as well as the number of electrons in its last layer , also determine the properties of that atom or substance. This property can play a decisive role in the mechanism by which the substance combines its chemical properties. For example, the properties of a metal ion are different from the atoms of that metal. So far, the role of the three factors of atomic number, mass number and electron arrangement of matter in determining the properties of electrons in the nanostructure of matter is influential. The macroscopic properties of a material, such as melting point, boiling point, and electrical conductivity, are determined by studying a sample sufficient to measure under normal nanoparticle conditions. This is not true for all materials, when the material size is reduced to nanometer dimensions, behavior and properties may be To be seen completely different from the same material in large dimensions. If a material with a slit structure of nanoelectronic devices with a scale of several tens of meters is reduced to millimeter dimensions, there will be no change in its melting point, color and magnetic properties, but this change when the material is reduced in size. It is seen in nanometers and the number of surface atoms in materials with scales larger than nanometers is very small, but entering the world of nanometers, the amount of these atoms is much higher than the total atoms of matter.
Conclusion :
Examining the band gap structure of nanoelectronic devices, in addition to introducing a method for researching the performance of one-dimensional systems, has made it possible to improve the electrical-optical properties of electronic components.
